M32 DIGITAL CONSOLE User Manual
Destination: The patch connector to which a signal is routed. See Patching.
Device: A diagram(s) in the I/O tabs representing a physical rack unit, such as a
line I/O, mic splitter, DN9696, AES50 etc. See Patching.
DI: Abbreviation for 'direct inject' or 'direct injection'. Signal is plugged directly
into the audio chain without using a microphone.
DI box: Device for matching signal level impedance of a source to mixer input.
Drag: A method of GUI operation, mainly for control adjustment. Also used for
selecting blocks of patch connectors during patching.
DSP: Abbreviation for 'digital signal processing' or 'digital signal processor'.
Any signal processing done after an analogue audio signal has been converted
into digital audio. Can be used to create, for example, compression, equalisation
etc., of a digital signal. A digital signal processor is a piece of equipment
specifically designed for carrying out signal processing.
E
E zone: Section in the input channel strip for controlling EQ parameters.
Effect: One of a number of audio processes that can be applied to a signal to
modify it, such as reverb, flanging, phasing, delay etc.
Effects rack: A virtual rack of internal processors. See Virtual rack.
Envelope: 1. How a sound or audio signal varies in intensity over time.
2. The visual representation of such, usually shown on a graph in a GUI
channel strip.
EQ: Abbreviation for 'equaliser' or 'equalisation'.
Equalisation: Adjusting the frequency response so that the levels
of all frequencies are equal or the same. Bass and treble controls are
equalisation controls.
EtherCon®: A cable connector for data transfer interconnections, which is more
robust than the basic RJ45.
F
Fader: Slider-type device for precise adjustment of signal level or volume of
a channel.
Fast strip: One of the strips in the input, mix and output fast zones. See Input
fast strip, Mix fast strip, Output fast strip and Fast zone.
Fast zone: An area on a bay that contains quick controls. See Input fast zone,
Mix fast zone, Output fast zone and Fast strip.
FB: Abbreviation for 'front-back'. A term used in surround panning.
Feedback: See Acoustic feedback.
Filter: A device for removing frequencies above or below certain levels.
FOH: Abbreviation for 'front of house'. The area in a theatre used by the public.
Used to describe a control centre being used to control the sound that the
audience will hear (and not the performers' monitor system).
Frequency: The number of times that a sound wave's cycle repeats within
one second.
Fricative: A consonant, such as 'f' or 's', produced by the forcing of breath
through a constricted passage.
From section: The leftmost area of the patching screen that contains the source
patch connectors. See Patching.
G
Gain: Another term for signal level.
Gain reduction (compressor): Decrease in gain when input signal is above
threshold. See Gain.
GEQ: Abbreviation for 'graphic equaliser'. See Graphic EQ.
GEQ rack: A virtual rack of GEQs. See Virtual rack.
Granularity: A measure of the size of components or a description of the
components comprising a system.
Graphic EQ: A form of EQ that has a number of faders for controlling the gain of
the audio signal. The faders are set at frequency bands that are evenly-spaced
according to octaves.
GUI: Abbreviation for 'graphical user interface'.
GUI channel strip: Right section of a GUI screen that represents the processing
area of the input or output channel strip selected to the control surface.
GUI menu: A menu selectable at either GUI screen by clicking the home button
(upper-left corner).
GUI screen: One of the M32's two screens, which comprise the GUI.
H
HPF: Abbreviation for 'high pass filter'. A filter that removes lower frequencies
from a signal, leaving the higher frequencies unaffected.
Hum: Undesirable low frequency tone present in a signal due to grounding
problems or proximity to a power source.
Hz: Symbol for 'Hertz'. A unit of frequency equal to one cycle of a sound wave
per second.
I
I zone: Area on the master bay that contains the operator-assignable
effects controls.
I/O: Abbreviation for 'input/output'.
ID: Abbreviation for 'identification'.
Ident: Scale marking, or gradation, around a control knob to help indicate the
current setting and to assist in accurate adjustment.
Impedance (Z): Opposition to the flow of alternating current in a circuit,
measured in ohms.
K
Kernel: For computers, the kernel is the central component of most
operating systems.
L
LCD select button: LCD button in the input fast strips and VCA groups, used for
channel/group navigation and selection, and operator feedback.
LFE: Abbreviation for 'low frequency effects'. Typically, the '.1' in '5.1 surround' is
an LFE channel.
LFO: 1. Abbreviation for Low-Frequency Oscillation, an electronic signal which is
usually below 20 Hz and creates a rhythmic pulse or sweep. This pulse or sweep
is often used to modulate synthesizers, delay lines and other audio equipment in
order to create effects used in the production of electronic music. 2. Abbreviation
for Low-Frequency Oscillator, the device itself which produces low-frequency
oscillation.
Linux: Also known as 'Linux kernel'. Operating system kernel used by a family of
Unix-like operating systems. See kernel.
LS: Abbreviation for 'left surround'. The left rear speaker in a 5.1
surround system.
M
MADI: Abbreviation for 'multi-channel audio digital interface'.
Master bay: Control area for masters, automation, comms, monitoring etc.
Also contains the primary navigation zone.
Masters: The three master channels (mono and stereo left and right) in the
master bay.
MB: Abbreviation for 'megabyte'.
MC: Abbreviation for 'master controller'.
Meter: Visual device to indicate the level of a signal.
Meters screen: One of the GUI screens. This is the default screen of the
master bay.
